摘要
A fiber mixture of natural fibers and binder fibers are blown from a storage container onto a first transport belt with a three-dimensional alignment of the fibers resulting in a fiber fleece. Thermally activatable synthetic resin granules are blown onto the fiber fleece and the fleece is defibered and remixed. The remixed fiber mixture is blown onto a second transport belt with a three-dimensional alignment of the fibers resulting in a mat. The thickness of the mat is obtained by the circulating speed of the second transport belt. The mat is transferred to an oven belt and is moved through a heating/cooling oven, for softening of the binder fibers and the synthetic resin granules, resulting in an intimate bonding of the wood fibers, the binder fibers, and the synthetic resin granules. The final thickness and the bulk density are set to specified ranges.
